From now through next September deer will begin using minerals again more than through next fall. February they will start using them more heavily and especially when antlers start growing and fawns start dropping is when they will use them the most.

Opportunity is missed by most people because it is dressed in overalls and looks like work.

Over the last few years of using the TR I've noticed that does start showing intrest in my Trophy Rocks aroung mid January. I think the does that are pregnant earliest are the first to start craving the minerals.

I may be opinionated...but, my opinion is the only one that matters anyway.
